The invention relates to a method for detecting an analyte present in a liquid specimen, including: injecting the liquid specimen into a detection chamber, the detection chamber having a non-zero volume enclosing polymeric beads covered with a reagent suitable for the analyte to be detected; capturing at least one image of at least one region of the detection chamber using a sensor; processing the image acquired by the sensor, which includes determining a texture level of the acquired image; and determining a concentration of the analyte depending on the texture level determined for the image.

The method is provided for characterizing agglomeration of particles in a liquid containing an analyte, including introducing liquid into a fluid chamber; mixing the liquid with a bifunctional reagent, lighting the fluid chamber using an excitation light beam extending through the fluid chamber in a longitudinal direction (X); acquiring at least one image using a matrix photodetector, each image including pixels (I(x,y), x,y representing the coordinates of a pixel of an image, the image (I(x,y)) being formed by radiation transmitted by the lighted fluid chamber; and calculating from at least one acquired image (I(x,y)), at least one indicator (Ind) characterizing the particle agglomeration. The photodetector can be positioned less than 1 cm from the fluid chamber, and during the calculation step, the calculated indicator (Ind) is representative of the intensity of the pixels of the image. The method advantageously allows for characterizing the agglomeration of particles in a liquid.
